OYRIL J. ATKINSON, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO INTERNA- TIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed November 2, 1906. Serial No, 341,695.

To all whom it may conce n.-

Be it known that I, OYRIL J. ATKINSON, a subject of the King of Great Britain, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Gas- Producers, of which the following is a specification.

My invention relates to improvements in what are commonly called suction-producers in the above class of invention, being those in which a current of air is caused to flow to the producer for the purpose of assisting combustion by the suction operation of an explosive-engine connected therewith and receiving explosive mixture therefrom, and it is designed to automatically regulate the supply of water to the vaporizer forming part of the complete producer in proportion to the demand for gas therefrom caused by the suction action of the engine in drawing in a charge of explosive mixture.

Referring to the accompanying drawings, Figure 1- represents a sectional elevation of an automatically-operable mechanism for controlling the supply of water to the producer, which latter is shown only in part; and Fig. 2 is a side view of a part of Fig. 1.

Similar reference-numerals designate the same parts throughout the several views.

1 represents a part of the scrubber, and 2 a portion of the generator or vaporizer through which the hot gases pass on their way from the producer (not shown) to the scrubber. Mounted between the scrubber and generator is a water-supply mechanism comprising a saucer-shaped disk portion 3, having a central tubular portion 4, projecting laterally therefrom and communicating with the interior of the scrubber by means of the opening 5 through the side of the latter, and-an external flanged portion 6, having openings to receive the bolts 7, by which the device is secured to the scrubber.

8 is a flexible wall or cover secured to the face of the disk by means of a clamping-ring ing arm integral with the ring at its upper edge and having a depending portion 12 arranged parallel with the face of the ring.

13 is a cup securedto the inner surface of the flexible cover in axial alinement with the tubular portion 4 by means of a stem 14, having nuts 15 at its inner end adapted to secure the cup to the cover and to adjust the stem longitudinally and at its outer end a bearing portion 16, slidably mounted in the end of the depending portion of the arm.

A coiled spring 17 is received by the tubular portion 4 and the cup 13 and operates in a manner to press the cover and stem outward. A feed-water pipe 18 is connected with the upper side of the arm 11 and with any source of water-supply, and the feed is controlled by means of a valve 19. Communicating with the feed-pipe at its lower end is a water-conducting pipe 20, having a flexible portion 21 near its upper end and its central portion received by an opening 22 in the body portion of the stem 14 in a manner to be swung from side to side as the stem is caused to move longitudinally. Below the delivery end of the pipe is a cup 23, secured to a part of the disk 3 and having two compartments 24 and 25, separated by the wall 26. A pipe 27 connects compartment with the generator, and a waste-pipe 28 communicates with the compartment 24.

In the operation of the device a constant flow of water is maintained through the feedpipe 18, its volume being regulated by means of the valve, and the water is delivered into either of the compartments in the cup 23, its disposition being determined by the adjustment of the delivery end of the conductorpipe 20, controlled by the stem 14. That portion received by the compartment 24 flows out through the waste-pipe, and that received by the compartment 25 is conducted to the vaporizer. At each suction-stroke of the engine gas is withdrawn from the scrubber and a partial vacuum formed therein, the degree of which is determined by the speed of the engine and also by the throttling of the air-supply to the producer by mechanical or other means, such as the formation of clinkers on the grate or a too dense packing of the combustible material therein caused by a too rapid combustion.

As the degree of vacuum varies more or less 9 and screws 10, and 11 is a laterally-projectpressure of the atmosphere is received by the flexible cover controlling the movement of the swinging water-conducting pipe, and the latter is thereby caused to deliver water to the compartment connected with the vaporizer when the combustible matter reaches a high degree of incandescense, and when the engine is drawing a maximum of gas from the producer and when the air flowing to the producer is comparatively unrestricted and the gas re uired by the engine is a minimum quantity t e spring operating upon the flexible cover causes the conducting-pipe to swing in an opposite direction, and the water is delivered to the waste-water compartment as described.

What I claim as myinvention, and desire to secure by Letters Patent, is

1. In a gas-producer of the type described,

the combination of a vaporizer, a scrubber, means for supplying water "to said vaporizer, said means comprisingafeedmuphaving two 'compartments openjat their tops and "separated by a dividing-wall, a pipe connection between one of said compartments and said vaporizer, and a waste-pipe connected with the other compartment, a pipe connected with-a sou-roe of water-supply and having its delivery end adapted'to swing hem one compartment to the other of said cup in a manner to deliver water thereto, means for swinging the delivery end of said pipe, said means comprisin a 'col lapsib le vacuuni charnber communicating with said scrubber and havinga yielding wall connected with "said swinging pipe.
